This report presents a Cost-Effectiveness analysis of water interventions in Bauchi state,Nigeria, with particular emphasis on pipeline and borehole (Hand pump) water supply schemes.Using the measures adapted from Whittington et al (2008), this study estimates the cost andeffectiveness measures such as time savings and health benefit aimed at reducing the incidenceof and death from, diarrhea disease. First, it conducts a BASIC CEA which compares the cost perhousehold per year of PWS with BWS program. Second, it performs a PROGRAM CEA todetermine the relative effectiveness of the programs. The cost analysis shows that BWS is lessexpensive than PWS. Combining cost and effectiveness, the cost-effectiveness ratio shows theBWS is more cost-effective than the PWS program.

Nevertheless, CEA is not sufficient to determine the most attractive intervention, since itcannot quantify cost and effectiveness in the same unit. Hence, a benefit-cost analysis, whichestimates the monetary value of benefits, is applied. The results of the BCA seem to supportthe evidence that emerged from the cost-effectiveness analysis.

A sensitivity analysis is then performed to determine the robustness of these findings. A onewayand multi-way sensitivity analyses (with worse and best case scenarios) performed on theresults show that BWS is more cost-effective and attractive. The study then concludes with arecommendation that in areas where there are high cases of morbidity/mortality fromdiarrheal, access to portable water and improved health outcomes in densely populated areascan be achieved by diverting resources from BWS to PWS, that is by increasing pipeline watersupply. The converse is true for sparsely populated areas with low cases of morbidity/mortalityfrom diarrheal. However, in mildly populated areas with moderate cases ofmorbidity/mortality, PWS and BWS can be implemented as complements.

Nigeria Economic Update (Issue 3)

Recently released inflation rate report by the NBS shows a further decline in consumer price index in December 2017. At 15.37 percent, the CPI was 0.53 percentage points lower than the 15.90 percent recorded in November 2017. The food sub-index decreased to 19.42 percent from 20.21 percent, indicating reduced pressure on food prices in the review period. Core sub-index fell slightly to 12.1 percent from 12.21 percent in the preceding month. Going forward, the ability of the Central Bank of Nigeria (CBN) to control inflation in 2018 may be hampered by monetary injections by the government and politicians towards budgetary expenditure and election campaigns, respectively.
